Stamping and Springback of PEMFC Metal Bipolar Plate
Recently, the key obstacle of proton exchange membrane fuel cell (PEMFC) development is the higher manufacturing cost. In a PEMFC stack, bipolar plate is a main and multifunctional component, which accounts for the 60%-80% of total weight and 30%-45% of stack cost. So the forming cost of bipolar plate will influence the entire PEMFC manufacturing costs. Metal bipolar plate, which can satisfy the requirement, can be used for mass production to reduce the cost. Finite element analysis (FEA) of stamping and springback for metal bipolar plate is studied by ANSYS/LS-DYNA to be feasible.
